FIGURE 3 Kaplan–Meier curves for OS (A) and PFS (B) of ED-SCLC patients with high or low expression of PD-L1. Kaplan–Meier curves for OS (C) and PFS (D) of LD-SCLC patients with positive or negative expression of PD-L1. OS, overall survival; PFS, progression-free survival; ED, extensive disease; SCLC, small-cell lung cancer; PD-L1, programmed cell death-ligand 1; LD, limited disease.
